ELECTRIC-RAI LWAY CAR.

y SPECIFICATION forming part of Letters Patent No. 426,708, dated April 29, 1890.

Application flied May 18, 1889.

To @ZZ whom it may concern:

Be it known that I, JOHN A. BRILL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Electric- Railway Cars, of which the following is a specification.

My invention has relation to electricallypropelled cars of the type having an electric motor in gear directly with one of the caraxles either by gearing between the axle and the motor armature-shaft or between the axle and a counter-shaft, which in turn is in gear with the armature-shaft.

Heretofore, so far as I am aware, the system of supporting said motor which is deemed the most advisable for use is to suspend or mount the motor partly on the car-axle and partly on the car-body or truck-frame-that 1s to say, one end of the motor has journalbearings on the axle and the other end is secured by a spring, flexible, or other connection to the car-body or truck-frame or a :lixture thereon, preferably one which is not subject to the action of the car-springs.

The advantage of such described system of hanging or mounting the motor is that the axle and the motor armature-shaft or the counter-shaft between them when used are maintained in due parallel alignment under all conditions of service, and the car-axles are independent of each other to admit of each conforming to the curves or irregularities in the line of Way, whereby 'the durability and efficiency of the motor and its actuated parts are enhanced. In practice it has been found, however, that the mounting of one end of the motor-frame on the axle is objectionable for the reasons, first, that the Weight of the motor on the axle causes undue wear of it and the motor boxes or bearings on the axle, and, second, that said motor boxes or bearings have to be unshipped and the motor temporarily secured to the truck-frame or car-body when it is necessary to remove the axle with its wheels and axle-boxes for the purpose of replacing or repairing the same.

My invention has-'for its object to avoid such described objections and yet maintain Serial No. 311,294. (No model.)

or secure the above-described advantages; or, in other words, it has for its object to so mount or support the motor that its armature and counter shafts are in direct gear with the axle, the latter is maintained in parallel alignment with the motor-shafts, and the axle with its wheels and axle-boxes are easily and readily removed from the car without necessitating unshipping or dismantling any part of the motor-frame, and the weight of the latter on the axle and wear of said frame and axle as heretofore is avoided.

My invention accordingly consists of the combinations, constructions, and arrangements of parts as hereinafter described in the specification and pointed out in the claims, reference being had to the accompanying drawings, wherein- Figure 1 is an elevation of part of a car with running-gear and fra-me suspended from the axle boxes and motors on said frame, and having` engagement with the axles in accordance with my invention. Fig. 2 is a sectional elevation 0f part of the same, drawn to an enlarged scale, showing more plainly the inanner of securing the motor in position and its engagement with the axle; and Fig. 3 is an elevation of the same, showing the manner of unshipping an axle without dismantling any part of the motor-frame.

A represents a part of the frame-work of a car or truck; B, the springs therefor, C, the axles, having wheels c and axle-boxes c; and D, the frame supported or mountedupon the axle-boxes c', all of which may be constructed and arranged for operation in any of the wellknown ways or as desired.

In the drawings, the frame D is shown having as a component part the axle-box pedestals d, which are of inverted-U-shaped form, to provide lower open ends for the recesses d', closed by removable bars d2, so that the axles, with their wheels and boxes, can be removed from the car for replacement or repairs, as fully shown, described, and claimed in another pending application iiled by me on the 17th day of May, 1889, Serial No. 311,294.

E represents the electric motor of any suitable construction. In the drawings I have shown its armature-shaft e in gear with a counter-shaft e', which in turn is in gear with the axle, said counter-shaft e having its bearings preferably in the frame of the motor E to .maintain the counter and armature shafts in parallel alignment. The motor E is wholly mounted upon the frame D, being suitably bolted to cross rods or bars, as necessary, said bolts being' illustrated at f. To give the motor a springsupport or to cushion it, I interpose rubber or other elastic cushions f and f2 between the frame D and motor E and between said parts and the bolt heads and nuts, respectively. The openings in the motorframe or those in the frame D, through which the bolts f pass, are preferably slightly larger than the diameter of the bolts, in order to admit of the motor having a longitudinal movement independent of frame D, as and for a purpose hereinafter set forth.

From the motor E project arms G, having bifurcated or yoke outer ends g, to provide vertical recesses g therein with lower open ends, into which the axle C passes for engagement with said arms G, so that the latter will maintain said axle in due parallel alignment with the motor-shafts. The arms G do not impose any weight on the axle, hence there is no wear of said parts; and when the removable bars d2 are detached from the pedestals CZ to remove the axle, the latter automatically releases itself from the guide-arms G, and no part of the motor-frame is disturbed or dismantled as such described removal is effected.

As the motors E on frame D have a slight longitudinal movement independent of said frame, the motor for each axle conforms to the lateral movements of the axle in passing around curves or at other points of the line, or, in other words, each motor and axle are independent of each other, which would not be the case if both motors were rigidly secured to frame D; but where only one motor E is employed for a car, said motor maybe firmly bolted to frame D.

From the foregoing it will be noted that the motor is in direct gear with the car-axle, and the latter is maintained in parallel alignment with the motorshafts without the motor being journaled to or imposing any of its weight on the axle, and that the latter may be removed from the car without dismantling any part of the motor.

It is obvious that my mprovements are applicable to other forms of motors and to all styles of cars and frames D or other like fixtures on the car or truck.

Vhat I claim ism l. In a car, the combination of a motor mounted upon and wholly or entirely supported on a frame not subject to the action of the car-springs, and having guide-arms in engagement with one of the axles of the car to keep said axle in parallel alignment with the motor shaft or shafts, substantially as set forth.
